Advance Information

LCD Segment/ Common Driver with Controller

CMOS

SSD1809 is a single-chip CMOS LCD driver with controller for liquid crystal dot-matrix graphic display system. It consists of 225 high voltage driving output pins for driving 160 Segments, 64 Commons and 1 icon driving-Common.

SSD1809 displays data directly from its internal Graphic RAM (160x65). Data/Commands are sent from general MCU through a software selectable 6800-/8080-series compatible Parallel Interface or Serial Peripheral Interface.

SSD1809 embeds a DC-DC Converter, an On-chip Bias Divider and an On-Chip Oscillator which reduce the number of external components. With the special design on minimizing power consumption and package layout, SSD1809 is suitable for any portable battery-driven application requiring a long operation period and a compact size.
